XK0-006 System Management Practice Question
A Linux administrator needs to find all files in /var/log that have been modified within the last 7 days and are larger than 10 MB. Which find command accomplishes this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
find /var/log -mtime -7 -size +10M
Both commands correctly find files modified within the last 7 days and larger than 10 MB. Option A uses -mtime -7 (modified less than 7 days ago) and option D uses -mmin -10080 (modified less than 10080 minutes ago, which is equivalent to 7 days). Both use -size +10M for files larger than 10 MB.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
find /var/log -mtime -7 -size +10M
Why this is correct
Correct: -mtime -7 for last 7 days, -size +10M for larger than 10 MB.
- ✗
find /var/log -atime -7 -size +10M
Why it's wrong here
-atime refers to access time, not modification time.
- ✗
find /var/log -mtime +7 -size -10M
Why it's wrong here
+7 means older than 7 days, -10M means smaller than 10 MB.
- ✓
find /var/log -mmin -10080 -size +10M
Why this is correct
Correct. This is functionally equivalent to option A; -mmin -10080 matches files modified in the last 10080 minutes (7 days), and -size +10M matches files larger than 10 MB.
